CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 760,265, dated May 17,1904.

Application filed February 5, 1904. Serial No. 192,072. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE F. SMITH, a citizen of the United States,residing at Baltimore, State of Maryland, have invented certain new anduseful Improvements in Chimhey-Gaps, of which the following is aspeciiication.

This invention consists of an improved concrete chimney-cap or otherarticle composed of two completely-formed and hardened concrete partswhich are united by connecting the exposed ends of wires embedded insaid parts.

In many concrete articles, such as arched chimney-caps, the liability ofbreakage in handling the same is so great that their use is practicallyprohibitive. I. have therefore devised a novel construction whereby theconcrete cap or other article may be made in sections or parts complete,not likely to break in handling, and with one or more wires embedded andwith ends exposed, which parts may be assembled at the place where thearticle is to be set up, at which time the parts may be united bysplicing or tying the wire ends together. I also provide an improvedbase for the chimneycap.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is an elevation of a chimney surmounted by one of the improvedconcrete caps. Fig. 2 is a sectional view of the improved cap and a baseon which the cap sets. Fig. 3 is a top view of the two parts of the baseand the cap, showing the wires spliced together. Fig. 4 is a broadsideview of one part of the cap, showing the exposed ends of the wires. Fig.5 is a perspective View of the improved chimney-cap base, one cornerbeing in section.

The finished chimney-cap is of the arched form, as seen in Figs. 1 and2, made of concrete material, and is composed of two equal separatesections or parts A A, each being one-half of the cap, as seen in Fig.4L. Each section is curved and has one or more wires Z) embedded in it,and the ends 6 of the wires project from the edge a that is to abutagainst the corresponding edge of the other section. Each of thesesections may be said cles or commodities.

to be an article in itself, because any number of them in this conditionare salable as arti- VVhen two of said sections are set upright on theirbase edges (Z and the wired edges 0 abut, the arch becomes complete, andthe wire ends I), projecting at the abutting edges, may then be splicedor united in any suitable way. To make the arched cap more complete,provision is made for concealing the united wire ends. This consists offorming a rabbet-groove 0 along the edge 0 that is to abut and arrangingthe wire ends 7) to project from said groove. By reference to Figs. 2and 3 it will be seen this results in the formation of a channel orfurrow extending across the apex of the arch. The wire ends may then beunited by twisting two adjoining ends together, as shown in Fig. 2, andthen bending said united ends over sidewise into the channel, as shownin Fig.3. The apex channel may then be filled with plastic concrete 6 tocover the said wire ends and to form a suitable finish at the top of thearch. When the plastic concrete becomes hard in the channel, the archedchimney-cap will be complete.

A base to support the concrete arch comprises a concrete slab F, whoseexterior edge will have any shape, such as rectangular in the presentinstance, to suit the chimney on top of which it is to be placed, as inFig. 1. This slab has an opening g, up through which the smoke from thechimney-flue will issue, and on two sides of said opening on the top ofthe slab is a groove or depression [0, into which the base edges (Z ofthe chimney-cap set, as seen in Fig. 2.

In order to strengthen concrete slabs for chimney-tops and prevent themfrom breaking. at the corners, an angle-iron of L shape is embedded ineach corner, as shown in Fig. 5 at the corner that is sectioned. Thisconstruction of concrete slab makes a durable finish for the protectionof tops of chimneys.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is

1. A section of an arched chimney-cap made of concrete and in the formof a curved slab, and provided with one or more embedded wires and theend or ends of said wires projecting and exposed at one edge.

2. A section of an arched chimney-cap made of concrete and in the formof a curved slab,

. section.

I 4. A concrete arched chimney-cap having base edges, and a concretebase-slab to rest upon the top of a chimney and provided with asmoke-opening and said slab having on top and at two sides of saidopening a groove or depression into which said base edges set;

5. A concrete arched chimney-cap having base edges, and a concretebase-slab to rest upon the top of a chimney and provided with asmoke-opening and with seats for said base edges and having angle-ironsembedded at the corners.

6. An arched chimney-cap comprising tw separate sections each formingpart of the arch and having an apex edge and each section provided withembedded wires whose ends project and are exposed at said apex edgetheprojecting Wire ends of one section being adapted to be united withthose of the other section.

7. An arched chimney-cap comprising two separate sections each formingpart of the arch and having an apex edge whereat the two sections join,and means at said apex for joining said sections and holding themtogether.

In testimony whereof I afiix my signature in the presence of twowitnesses.
